will this outlet box work for metal studs.

Asked by: Chris
I don't see why you could not mount this on metal stud. Whats more important is that you are not installing this in "rough use" area, where an outlet for example will be under constant assault. Given some other reviews stating that the box is essentially unstable, the screw mechanism sounds like it won't hold up to prolonged abuse. I have never had an issue the handful of times I have used these so far. But I would never use one of these where I thought it might come under constant assault. And there are ways to modify and install these for use in "old construction", where replacing the whole shootin match if needed is a snap. So mounting this on a metal stud is probably not the issue. Mounting it properly and for the right reasons will be the real concern.

Do you completely knock out two upper corner panels(for one outlet) or just bend them back to firmly hold the wires?

Asked by: bolee
These are meant to be knocked out and removed completely. But as an electrician, I can tell you that I remove even the tabs from plastic box's that are not meant to be removed.

1-Gang 21 cu. in. Non-Metallic Wall Box with Adjustable Bracket is rated 3.8 out of 5 by 9.
Rated 5 out of 5 by from Wow, so much to say here while trying to keep it short. I’ll do my best. I’ve was an electricia... Wow, so much to say here while trying to keep it short. I’ll do my best. I’ve was an electrician in my previous career, and I have done electrical work for more than 20 years. I don’t know how “new” of an invention this is, but I can tell you that in all the times I have bought box’s at the depot, I only ran into these beauties fairly recently. They are a specialty item, designed primarily to address an age old problem. When your wall covering is thicker than “normal”, you need to figure a way to mount the box at a proper depth. There are many options that I have seen employed. Few are exactly satisfactory and virtually none of them are pretty. Most commonly, the box just gets buried too deep and some type of standoff is used to make up the difference. I took the time to say all of that in order to address some of the negative reviews. First, I would hope given the price difference that people are not using these in place of a good ol nail on under normal conditions. But for those complaining about the box pulling out or pushing into the wall when you plug and unplug a cord into the outlet, this is without question installation error. There is no reason if these box’s are installed properly, (and importantly, for the right purpose), that there should be any more play than with any other style of box. In fact, these boxes are remarkably stable given their Achilles heel. They do have an Achilles heel however, and that is where the screw connects to the metal bracket. The reality is, the stability of the box relies solely on a fairly anemic screw, and a really underwhelming bit of engineering where the screw screws in. There is very little meat holding the box firmly in place with the metal bracket. So I suspect that under rough use, such as the constant plugging and unplugging of cords to and from an outlet which may occur in a shop setting, that the screw may be prone to disengage from the metal bracket, essentially breaking the box. I mean to say, if that screw mechanism fails, the whole box is pooched. I submit however that these “Specialty box’s” were not designed for rough use, and under typical residential usage, these box’s are fine. I would not use them in a shop where the outlet will be under constant assault. I would not use these in a house setting where the outlet is under constant assault. There are time honored and sturdy methods, if not exactly pretty, that will hold up to abuse without issues, or even the possibility of issues. But installed correctly and for the right reasons, these boxes are handy as all get out. And with a bit of ingenuity, I have found that these boxes can be modified and used to turn an otherwise MISERABLE repair job, into a piece of cake. I have used these box’s a number of times now to great effect. But as is the case with pretty much everything, this design is a not a silver bullet replacement for everything that ever came before it. It’s instead a very handy additional option to have available. A++++++++++++++++ Will Buy Again.

Rated 1 out of 5 by from Do Not Recommend Great concept but has fatal flaw. The box gets pushed in or pulled forward when plugging in or unplugging an appliance, in my case, simple things such as an alarm clock, small lamp etc. I wish I knew this before I installed 20 of them in my new home addition. I wonder if they actually tested these boxes for performance before commencing mass production and sales.

Rated 2 out of 5 by from Don't buy. I installed six of these before putting up new drywall. As others have said, the desig... Don't buy. I installed six of these before putting up new drywall. As others have said, the design of these boxes is flawed. While the metal bracket is very sturdy, the sliding mechanism creates too much play, causing the box to wiggle, especially with those screw-less Decora plates. Wrecking my head now about how to fix this.

Rated 5 out of 5 by from best box on the market These boxes are awesome because your can adjust the face of the box to the finish wall as required by California code. This feature insures the secure fit of the outlets or switches you attach with no gaps behind the cover-plate.

Rated 5 out of 5 by from easiest install ever In a recent remodel I used these and even though they were a little more cost wise was thoroughly sold on them. They are without a doubt the easiest to install/and or reposition before securing, and the debt adjustment makes it ideal for applications where the finished wall has not been decided upon.

Rated 1 out of 5 by from Not suitable for receptacles I installed 25 throughout my workshop. The reason I went with these is because didn't know if I would add wainscoting at a later point. Therefore I didn't know the exact the thickness of my inside wall at the time of the electrical installation. If you plan use a heavy duty receptacle, one that will actually hold your plug DO NOT USE THESE BOXES! It will move back and forth in the wall, and I can only estimate that it will be a matter of time before the flimsy threads on every one of these break and I will have to replace all of them. I would not recommend these to anyone to use for receptacles.

Rated 5 out of 5 by from Very Handy Box As others have said this box is particularly handy because of the depth adjustment. I recently ran across this box and will use it on future installs.
